Definitions

  • the invention relates to a device and a method for pumping a flowable mass, in particular a consumable such. viscous fat masses.
  • Devices for pumping such masses have a pump chamber with an inlet opening and an outlet opening.
  • a piston is movable back and forth. By moving the piston in the first direction (outward movement), mass can be sucked into the pump chamber via the inlet opening. By moving the piston in the second direction (movement) mass can be expelled from the pump chamber via the outlet opening.
  • the pump housing and the piston can be designed differently.
  • the piston movement in the interior of the pump chamber is a rectilinear displacement of the piston along a displacement axis or a rotational movement of the piston about an axis of rotation. In this case, the opening and closing of the inlet opening and the outlet opening must be coordinated with the movements of the piston.
  • these openings are opened and closed by means of a slide valve or a rotary valve.
  • the functions of the suction and ejection of mass and the opening and closing of the openings can be achieved with a coordinated shaping of the piston and the pump chamber also by a combination of linear piston movement and rotational movement of the piston. This is referred to as stroke / rotary piston.
  • stroke / rotary piston On the DE-A-10 2005 004 785 reference is made to what is considered to be the closest prior art.

  • the two relative to each other and relative to the body movable body allow a simple construction of the device.
  • the volume of the chamber within the body is variable by moving at least one of the two bodies, and the position of the chamber within the body is changeable by moving both bodies.
  • the chamber can be brought into fluid communication with the inlet opening or with the outlet opening.
  • the inlet opening or the outlet opening can be blocked by positioning one of the bodies in front of this opening. Since the first body and the second body each sealingly abut against an inner wall and slidably against this inner wall, they can block openings attached to this inner wall like a slider.
  • the chamber volume may be increased to effect suction into the chamber by moving the two bodies away from one another, or the chamber volume may be reduced to effect ejection action out of the chamber by moving the two bodies towards each other ,
  • the inventive device is characterized not only by its simple structure, but it is also very flexible for various tasks. Since the two bodies are independently movable, many different effects can be achieved by the device. Thus, e.g. Both at the inlet opening and at the outlet opening a suction effect or an ejection effect can be achieved without further ado, whereby the pumping direction or conveying direction can be reversed. Also, the change in the pumping volume per cycle or the pump stroke can be easily changed by determining the minimum distance and the maximum distance between the two bodies accordingly.
  • the first body and the second body can each be connected to a servomotor drive.
  • the high positioning accuracy, reproducibility and programmability of servomotors can thus be passed on directly to the device according to the invention.
  • the device preferably contains stops for limiting the movement of the two bodies.
  • a stop for limiting its forward movement and a stop for limiting its movement can be provided for each of the two bodies. Due to the elasticity of such a pneumatic drive, although the timing of the movement of the two bodies changed between their two extreme positions, but not the Pump stroke or the pumping volume per pump cycle. For many applications in which the pumping volume or the dosing accuracy and the total time of a pumping cycle between suction and ejection of a certain volume of the flowable mass are specified, therefore sufficient pneumatic actuators.
